T0 all whom itmay concern:

Be it known that I, JACOB Hansen, a; citizenof the United States, residing. atNew York city, N. .Y., have invented certain'new and useful Improvements.- in: Gat'et-Locksfor Dra-wbridgesxand Roadways; ot-whi'ch thefollowing; isa clear,;full,-and exact description.

This. invention relates, to locks, and particularly to means; forsecuring-inclosed- 10 sition the swinging gates of draw-bridges, roadways, etc. i r

The gates which are. locatedupondrawbridges and roadways to prevent. the passage of vehicles at certain times as, for example, when the draw is open, are usually arranged toswing from the two sides-of the bridge or roadway toward the center, andmeans is usually provided for locking the adjacent ends of the gates together. ItQsometimes happens that the gates of a draw-bridge. or roadway are closed. infront of a moving; vehicle which. cannot be stopped intime: to preventv running into the-gates and sometimes drivers of vehicles fail to see gates or to allow sufficient distancein which to stop, andthus come into collision therewith.

With the locking means: for gates heretofore.v

provided, the, usual resultof a collision of this sort is that the gates are brokenopen and thus noprotection. is provided: for the 7 bridge or roadway,-.-often.- with disastrousresults to the} vehicle which! collides with the, gates. j j

A particularobject of: the: prescntiinvention isto provide locking meanszfor draw bridge: gates and the like, which will e'fi ec-' tivelysecure the, gates in closedposi-tion, and yet, which, in the; event of collision, will pro vide .for yielding; movement. of the gates. sufiicient to bring thevehicle to. a stop.

Other; objects and. important; featuresv of the inyention will appear from: the follow ing description and the; claims. whenconsid ered in connectio with the. accompanying,

Eenewed-August 21 1917. Seria1-No..187,485.

Fig. 4' is. a perspective view of thebolt sitionatone side of theroadway to a-cl'osed position in; which they are in alinement'w and inwhich their ends are rated, as shown in Fig. 1.

The illustratedlocking means is-preferably located between the-endsof the gates and, as shown, comprises a bolt guide. 14 and a'keeper 16,-the; bolt guidebeing provided with. a. vertically sliding bolt. 18 carried by a strap or bar 20: to which a second operating bolt 22 is connected, thisbolt being provided at, its lower end with an ofisethandle 24 connected to said boltiby a crank arm' 2.6.

preferably .sepa- By lifting up on the. handle; 24, theb'olt 18 may be withdrawn' from'thebolt receiving opening in the keeper 16, as shown indotted linesin, Fig. 3, and the. handle may then be; turnedto' sWing'the-bolt 18 over a solid por tion ofthebolt. guide. inorder to .retainit in elevated position. i

The :bOlt guide. 14 is providedwith a'basie. QS' haVi-ng a fiat facewhich abuts'thetend of thegate 2', andthe keeper 16 is: provided with a base 30 having a flat fa cewhich abuts theend of thegate 4. Means. is'provided formaintaining the-3-bases- 28 andi 3.0 normallyzin rigidabTu-tting relation to: the respective; gates", whereby when the bolt 18' is; inlockin g position, the-gates, willbe maintaincd, in. rigid alinement. The illustrated means for maintaining the bases 2&and-3Q in abuttingrelation to the-gatescomprises springs 32 acting upon plungers 34, eachof. which comprises a boltpas'sing through the base of the member upon which itoperatesandahaving a" head 36' bearing upon the outer face: of this base, awasher 38 against" which. one end of "thespring bears, and a nut."

10910?confining:the washer upon the-bolt.

m an two ab g ce al memb zz tea straps 48, the straps upon opposite sides of the central portion 44 of the gate havmg out-turned portions which abut said memher at and which are connected through said member by bolts 50..

It will be noted that the plungers 84 are connected to the bases of the locking members'upon opposite.sides of the point of engagement of the bolt 18 with the keeper 16, and that thus they serve to hold the bases normally in rigid relation to the gates. In the event of unusual pressure upon either side of the gates, the springs 32 will permit the base members 28 and 30 to rock about one of the edges of their abutting faces as the gates tend to swing into separated relation, thus permitting a limited swinging movement of the gates without breaking oi the lock or injury to the gates. When the force which has caused the gates to be moved out of alinement ceases to act upon the gates, the springs 32 will tend to force the gates back into alinemeni; again.

What I claim 'asnew is:

1. In combination, locking means com prising a bolt guide and a keeper, relatively swinging supports for the respective members of said locking means, and means for normally maintaining said members rigid with said supports, said means being constructed to permit a yielding relative movement of said lockingmeans' and said supports in certain directions.
